摘要：This paper first generalizes the significance and present research situation of the building shadow extraction and elimination method. Then, an approach of automatic extracting shadows of building from remote sensing image is proposed, which based on the method that grey level statistics is done in one side of the structure lines. The approach, which combines constraints of grey level, geometry and context, and others assistant information, realizes the shadow extraction of buildings. Finally the IKONOS images are experimented to extract shadows of building. Results of the experiment show that this approach is effective and robust
